Unable to call base interface getter with cast without explicit setup.

[gurustron]

public interface IQueryModel : IQueryModelImmutable
{
    public int Property1 { get; set; } 
}

public interface IQueryModelImmutable
{
    public int Property1 { get; } 
}

Mock<IQueryModel> mock = new Mock<IQueryModel>
{
    // CallBase = true // does not affect things, can be commented in/out
};
// mock.Setup(m => m.Property1).Returns(100);
mock.As<IQueryModelImmutable>().Setup(m => m.Property1).Returns(100); // works only if both setups are present
IQueryModelImmutable toTest = mock.Object;
Assert.AreEqual(100, mock.Object.Property1);
Assert.AreEqual(100, toTest.Property1);

Tried different combinations of setting up only one of interfaces and using/ not using CallBase - only working one is when both interfaces get_Property1 is set up explicitly.

CallBase has no effect in this case because there is no base implementation to call; all your interfaces' members are abstract.

If you implemented those interfaces yourself, you wouldn't try to invoke base.Property1, right?

@stakx it's not about CallBase. If you remove it still setting up both methods is needed. Casting to base interface is not working otherwise.

If I've implemented both those interfaces in one class - casting it to base interface would have worked.

@stakx ?

I don't get it. If it' not about CallBase, why is it mentioned everywhere, including in your question title? I suggest you rephrase the whole thing and remove whatever isn't actually related to your issue.
